Be it known that I, Bion R. BONNEY, av

in road graders, and has'for its object to provide a machine by use of which the rough or uneven surfaces of highways may be made smooth, or for use in forming new roadswhich are convexed in cross-section, the structural parts to be few and so arranged that Vthey will beA convenient inuse` and may be economically manufactured.

The invention includes the combination with' a vehicle of a plurality of blades mounted thereon and disposed inclinedly to A'the longitudinal axis thereof and at di'erent distances from its front, so that the excavated earth may be conveyed transversely of the vehicle while moving forwardly, toward the middle of the road, means being provided to change the inclination of theblades, transversely of the vehicle, as may be required. Also the invention includes means for throwing a furrow inwardly of a roadway at the gutter or sides of a roadway, this being quite necessary where sods or turf are encountered.

With the foregoing objects in view and others to be hereinafter mentioned, the invention presents a novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing, wherein,-

Figurel is a planview of the machine, and Fig. 2 is a view of the same in side elevation. Fig. 3 is a section on line 3 3 of Fig. 4. Fig. l is a broken away plan view showing an adjusting plate andits connec* tion with the inclined cross-bar of the vehicle frame. Fig. 5 is a detail showing a plan view of the sod-cutter.

Referring now to the drawing for a `more' particular description, I provide a vehicle frame of any suitable construction, but pref-I erably havingparallel sidebars orplatesh and 7, and asuitable'number of inner frame plates disposed parallel therewith, as indicated at 8, 9 Vand vl0, and a Vfront cross bar 1l disposed inclinedly with reference thereto, angle iron preferably being used for these parts, a rear axle l2 being provided whichmay have bearings inthe rear ends of the parallel frame plates or may b'e:secured thereto, as desired; and the rear Wheels 13, preferably, are arranged to rotate on the axle.

Extending forwardly from the frame thus described and connected with the cross-bar l1 is a secondary frame for the comparatively short front axle 14, the wheels lro-V tatable thereon havinga limited diameter as compared with-the rear wheels, said axlev and the tongue 16 being adaptedto swing while'connected by a kingbolt 17 with the plate 18, disposed in line with thelongitudinal axis of the vehicle and supported by the pair of bars 19, "inclined stay rodsy 20 and 21 being employed for supporting this secondary frame.`

It will be understood that the provision of the inclined cross-bar and its `connections thus described is for convenience when turning about for a reverse direction of movement of the vehicle, since the machine is for excavating and removing the earth from the sides to theV middle of a roadway, and on account of the construction, the machine may be turned forY moving in a reverse direction uponan area less than ordinary.

At 22 are indicated a plurality of scraper blades normally disposed parallel with reference to each other and inclined with refer ence to the axis or lineof travel of the ve hicle. Any suitable-means may be provided for pressing these blades into the ground, the means herein shown for this purpose being pockets or receptacles 23, one of these receptacles being lsecured upon and atthe rear side of each blade for containing a weight, such as rock or earth, eachblade, alsoV being inclinedV forwardly and downwardly, for the same purpose.

Each blade is provided with a tongue or' goose-neck, consisting of fa :pair of.- arms or rods 24 and 24J, the arms-24 havinga less length than the arms 24, and each pair of arms being connected with one of the blades and extending convergently in a forward di- Y rectionfor a mounting upon a tie-plate 25, the tlc-plates being connected with the crossbar 11 at longitudinal intervals thereof byv means of staples arranged in pairs as indicated at 26 and 27, means being provided for changing the inclination of each arm 24 and each scraper blade since the staples 27 maybe mounted, as shown in Fig. 4 or mayV engage 1n one of the apertures 2SV and "29 formed in the tie plates andrin the arms 24 which, in operation, would result in less re- `sistance or stresses being directed to the blades.

Itwillbe understood that the blades will engageVY in the ground when the Amachine moves forwardly, and that the dislodged or excavated earth will, on account of the inj clination mentioned for the blades, be conveyed transversely of the machine substan- Y tially from the side bar 7 to somewhat beyond 'the side bar 6,' said blades being of suiiicient length so that a part of each rearward blade will be disposed in the plane and at the rear of a part of a blade disposed forwardly thereof, vthe resultY being that the ground scraped or operated uponk will have a smooth surface, the'flanges on the vehicle Wheels tending to resist side stresses. Also it Vwill be understood thata greater or lesser Y' degree of flexibility is provided by reason for several reasons.

of the employment of a plurality of blades as compared with'a single long blade, since the particular mounting provided by the tieplates and staples permit the blades to enter the groundV independently of each other,

which tends to form a roadway convexed in cross-section. Y

Y Numeral 30 indicates a plow-member for forming a furrow or channel below the side rail 7 in which the rear wheel, adjacent to said side rail, may engage, for disposing the vehicle frame inclinedly transversely ot' the travel of the machine in a manner to throw the furrows inwardly of the machine at the front of the 'foremost blade, Y

The member 30 thus described is quite necessary in vthe operation of the machine Where sods are cncountered they must be cut and a channel or gutter must be formed at the sides of a highway since the roadway is to be convexed in cross-section, said channel also permitting the foremost blade to readily enter the :causing the disks 35 t0 enter the ground and VYthe weight 37 may be adjusted longitudinally of the arm 3G, its bolt 38 being adapted to engage in any one of the apertures 3S), for regulatmg the downward pressure upon the disks. Any suitable means may be provided for elevating the blades and disks, Vas the cables or strands 40, 41,42, 43 and 44 engaging suitable pulleys and under control of levers 45 and 46 this being necessary when turning about for a yreverse movement of the machine, or when driving the machine from one location to another.

Having fully described my invention, what I claim and desire to secure by Letters Patent is,-

1. In combination with a frame having substantially parallel side plates and a cross-bar disposed at an oblique angle to and connected with the side plates, said frame being provided with front and rear wheels, tie-plates disposed at longitudinal intervals of and connected with the cross-bar, a plurality of scraper blades,A a plurality of tongue-members each consisting of a pair of arms of unequal length mounted upon and adjacent to the ends of a scraper blade and extending forwardly convergingly for a mounting upon a tie-plate for disposing a scraper blade inclined to the longitudinal axis of the frame, an earth-working member including a weighted arm pivotally mounted upon a side plate and provided with axially mounted disks disposed at the front of one of said scraper blades in line with one of the rear wheels, means for elevating said earth-working member and scraper blades with reference to the frame, and means on the tie-plates connected with the cross-bar for adjusting the degree of inclination of the scraper blades transversely of said Jframe.

2. In combination with a :trame having substantially parallel side plates and a crossbar connected with the side plates, said frame being provided with front and rear wheels, tie-plates disposed at longitudinal intervals of and connected with the crossbar, a plurality of scraper blades, a plurality of tongue-members each consisting of a pair of arms of unequal length mounted upon and adjacent to the ends of a scraper-blade and extending forwardly convergingly for a mounting upon a tie-plate for maintaining the scraper-blades at intervals longitudinally of and inclined with reference to the side plates, an earth-working member including a weighted arm pivotally mounted upon a side plate and provided with axially mounted disks disposed at the front of one of said scraper-blades in line with one of the rear Wheels, means for elevating said earth- Working member and scraper-blades with reference to said frame and means for adjusting the scraper-blades transversely of the frame.
